So far, the national housing prices listed nearly twenty billion yuan of funds to the" mining", almost to the universal for ore and so crazy. Mining limestone resources business opportunities, milling machine at a number of industries. Mineral resources used in a variety of industries, including the use of the most extensive use is the most extensive limestone. Limestone is a sedimentary rock composed mainly of calcite, throughout the country have distribution, mining easy and low cost, and easy processing and comprehensive utilization.In recent years Chinese mill industry continues to rise, also led to a milling machine technological progress. Limestone processing, selection of different material fineness stone mill, can be produced for a variety of purposes of limestone powder, thus the maximum to meet the various sectors of the processing requirements. The effect of material"s hardness. Abrasive hardness wear rate of materials was investigated. The extent of this impact is the main material hardness and abrasive hardness of H. H. The ratio for the mark, along with H / H. Change, material wear mechanism changes. Abrasive shape ( sharpness ) to wear also has obvious shadow ketone. New broken quartz sand and river sand, new broken quartz sand on the wear of materials is more intense. Because of all kinds of abrasive shapes are difficult to measure and quantitative difference, generally only qualitatively the abrasive is divided into three types: the sharp shape, polygon and the circular blunt. Under the same condition of hardness, sharp abrasive material shaped to blind loss most violent, wear mechanism of micro cutting; polygon on the wear of materials is the second, wear mechanism for micro cutting and ploughing; circular pure form of abrasive wear mechanism of fork," plow Amoy. Abrasive size size on wear also has a certain impact. When the abrasive in a critical dimension, the volumetric wear for grinding section size increases sharply increased in proportion; when more than a critical size, increased significantly reduce wear.hoist bucket: http://www.china-hxjq.com/p123.html spiral washer: http://www.crusher-machine.com/n118.html Henan Hongxing mining equipment limited production of Raymond mill, YGMX superfine grinding mill, high pressure powder mill, powder mill, ball mill, superfine grinding equipment, mainly for all kinds of ore processing, material particle size range from a few to three thousand, high yield, stable performance. A tripod heavy you provide more complete mill production line equipment and solutions, the company is the production of industrial milling machine equipment in China come out in front, whether from the production strength or quality of equipment and services, a tripod all got social all circles and government departments for approval, in environmental protection, energy saving, high efficiency and more productive, for customers to obtain the economic benefits to provide security, industry has won the praise.
